Value Collection 1057351 Taper Length Drill 0.6875 in

Product Description

The VALUE COLLECTION 1057351 is a taper length drill bit ground from M35-grade HSS-E cobalt high-speed steel and finished bright/uncoated for general-purpose drilling applications. At 0.6875 inches (11/16 inch) in diameter with a 118-degree split-point angle, it delivers clean entry and efficient chip evacuation in a wide range of workpiece materials. The extended flute length of 6 inches and overall length of 9.25 inches give machinists and tool-room operators the reach needed for deeper bores that standard-length drills cannot achieve. This bit is suited for manual drill press work and CNC applications requiring a longer reach-to-diameter ratio.

This taper length drill is applied in job shops, maintenance departments, and production environments where drilling depth exceeds what jobber-length bits can handle. The M35 cobalt content raises heat resistance compared to standard M2 HSS, making it a practical choice when drilling harder ferrous metals, stainless steel, and tough alloys at moderate to high feed rates. The 11/16-inch shank matches the bit diameter and seats securely in standard drill chucks or collet systems.

Key Features

• M35-grade HSS-E cobalt construction for improved heat and wear resistance over standard HSS
• 118-degree point angle suited for general-purpose drilling in ferrous and non-ferrous materials
• 6-inch flute length provides extended reach for deeper bore applications
• Bright/uncoated finish maintains sharp edge geometry without coating buildup
• 11/16-inch shank diameter matches bit diameter for balanced chuck grip
• 9.25-inch overall length accommodates setups where jobber-length drills fall short

Compatibility

Designed as a general-purpose taper length drill bit compatible with standard drill press chucks, CNC spindles, and hand-held drilling equipment accepting an 11/16-inch shank.

Installation Notes

Installation and use of this drill bit should be performed by machinists or qualified trade personnel familiar with drilling speeds and feeds for the target material. Secure the shank fully in the chuck or collet before operation and verify runout before beginning the cut. Use appropriate cutting fluid for ferrous or stainless workpieces to extend tool life and manage heat. Follow applicable shop safety standards and machine-specific operating procedures at all times.
